FRANK W. GARLSON, OF CHICAGO, ILLINOTSL PLUMBING sYs'rEr/r.

To all whom it may" concern:

Be it known that I,- FRANx W, CARLsoN, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois,'have invented certain new and useful Improvements in Plumbing Systems, of

which the following is a specification.

It has been commonpractice in plumbing systems in the past to provide each lavatory and other fixturewith a self sealing water trap to prevent the gases and odors from escaping intothe room, and also to provide a vent pipe in connection with the waste pipeto preserve the water seals at the fixtures and to permit escape of the gases outside thebuilding. But in actual practice ventilation for which it is intended.

the vent pipe may remain concealed for some time. Meanwhile the water seal is drawn out of the trap by siphoning action" in the waste pipe and the poisonous gases and noxious odors are permitted to escape through the fixtureinto the room.

My invention has for its objects to dispense with the vent pipe,to provide a plumbing system in which the gases and odors will escape through the waste pipe, andto prevent the waterseal in the trap for each fixture connected with the waste pipe from bethrough the waste pipe.

My 'nvention also has. for its object to reduce the cost of installing a plumbing system by eliminatingthe vent pipe usually as sociated with the'waste pipe and to provide forchecking the flow of waste through the waste pipe at intervals to break the force thereof and to prevent any. siphoning action on the water seals of the fixtures.

And the invention also has for itsobject to;

' b'aflie in the path of waste falling .down "through the pipe The projection .22 is provide an improved connection whereby one or more fixtures can be easily and quickly connected with the waste pipe, and-which .will permit .access to the pipe for cleanlng' and other purposes.

" Referring to the drawings ,6 is a waste pipe which' connects with the sewer pipe 7 and extends upward through the building and has an outlet- 8 above the roof 9. The

'usual fixtures, such as a wash bowl 10, sinks 11, 12 and wash tub 13 are connected with the wastepipe, each fixture being'pr'ovided according to the common practice with the self sealing water trap 14:- 1 v In the drawings I have only shown a few fixtures connected with the waste pipe, but

it will be understood that the invention is just as'well adapted for high buildings, such waste pipe at each story, as it is to smaller buildings, such as private dwelllngs. j

The connection comprises a short pipe section 15 interposedin-the'waste pipe and forming a part thereof and provided with an enlarged chamber 16 between its ends.

This chamber is substantially rectangular in shape, greater in width from side to side than from front to rear, and formed by the outwardly extending side walls 17-17 and the parallelfront and rear walls18-18'. 1 Threaded inlet openings 19-19 are provided'in the front and. rearwalls of the 'connection (Figs) 2-3) for the fixture "pipes.

In one of these openings, 19 for example, I- provide a hollow plug20 exteriorly threaded to engage the threaded opening 19, and interiorly threaded to receive the fixture pipe 211* Thisjplug'has 'a' projection "22 which extends inward across the chamber'16 to form a check or located :adjacent the top of the plug and "above the opening therein, the latter. beingeccentrica'lly disposed in'the plug so that In the accompanying. drawings I have the projection may: be located below the,

top of the plug sufficiently to have a width pipe and without obstructing the opening in the plug. The opening 19' in the rear wall of the chamber is smaller than'the opening 19 in the front wall'and corresponds in size with the opening in the .plugto receive the fixture pipe 21.

This opening 19 is eccentric to the opening 19 and is diswater seals out of thetraps.

If only one fixture is to be connected to the waste pipe the connectionmaybe provided with opening 19 and a solid plug,0 r

' the opening 19 may be omitted or plugged and connection made with the hollow plug 20 as shown.

I may construct the. connection as illustrated in.Fig. .4, with inlet openings 23 at the sides, a solid rear walland a solidjplug 24. This form of connection is suitable where the waste pipe connects with the sewer pipe and for connection with the wash tubs in. the basement of the. building. The plug can be removed to permit access to the sewer pipefor cleaning the pipe whenever it becomes clogged with grease and other waste matter.

In practice the waste passing down through the waste pipe is checked and broken up and diverted at each fco'nnection by the projection 22. This projection is located above the fixture pipe openings so that the waste is divided thereby into two streams and diverted to opposite sides of the chamber away from the fixture openings. 'By thus interrupting and breaking and diverting the flow of waste, I prevent it fixture traps. Thisenables the use of the waste pipe to carry off the gases and odors without danger of having. the waterseals in the fixture pipes destroyed andpermitting necessity of'using a vent pipe toflprevent the waste from siphoning out, the i'water seals, and I also avoid the danger -of,using permit the water seals to besiphoned out of the traps without 7 the knowledge ot .the

occupants of the building. 1

My invention 'greatlyreduces the cost of a waste pipe installation and vat the ame time provides a reliable sanitary installation. -.The waste water flowing interruptedly down the waste pipesubjects. thesystem to 'a-..'flushing and cleansing, action.,which,keeps the waste pipe free and Tunobstructed .and

3 in a sanitary condition.

-I am aware that changes in the form, andv propdrtion of parts and the-details of 'fall construction of the connection and in the arrangement and disposition of the connection in the system may be made without departing' from the spirit or sacrificing the advantages of the invention and I reserve the right to make all such changes as fairly within the scope of the accompanying claims.
